Abstract Background Interproximal reduction (IPR) is a treatment option for orthodontic space gain. The attainment of prescribed objectives in aligner treatment may require IPR that is accurately performed both qualitatively and quantitatively. Objective This study assesses the in vivo accuracy of IPR carried out in 10 orthodontic practices as a method of orthodontic space creation. Methods A comparison of proposed and achieved amounts of IPR completed (accuracy), the accuracy of IPR within and between upper and lower dental arches, and the accuracy of IPR within and between posterior and anterior arch segments were performed using 3-dimensional digital study models gained via Align’s® ClinCheck. Results The findings indicated that IPR was routinely underperformed by all practices studied. On average, the amount of IPR achieved represented only 44.0% of the total prescribed per tooth in the sample assessed, with a mean discrepancy of 0.16 mm per tooth. There were statistically significant differences only between the overall anterior and posterior groups (p < 0.01) and between maxillary anterior and maxillary posterior groups (p < 0.01); however, these were not clinically significant. Significant differences in IPR performance were noted between different orthodontic practices. Conclusions This study demonstrates that the clinical performance of IPR in 10 orthodontic practices consistently fails to achieve the prescribed amount often by large variations. The effect of this under-performance on clinical outcomes remains to be quantified.

Abstract Objective: The present study aimed to determine how the popularity of ‘Do It Yourself’ (DIY) aligner videos available on YouTube relates to authorship, video content, quality and reliability, and to determine why DIY aligners appeal to consumers. Methods: The Google Trends website was interrogated to identify the most frequently used search terms regarding DIY aligners which were subsequently applied to a search of the YouTube website. One hundred twenty-three videos were assessed for completeness of content, reliability (using a modified version of the DISCERN tool) and quality using the Global Quality Score (GQS). The relationship between the variables and authorship, popularity, financial interest, and recommendations were assessed using Pearson Correlation Coefficients. Results: Laypeople produced the majority of the videos (73%). Dentists/Orthodontists uploaded only 4% of the videos, and dental professional bodies uploaded none. Most videos (86%) were content poor, unreliable (average DISCERN score of 1) and of low quality (average GQS of 2). The more popular, reliable and superior the quality of the video, the greater the number of views, likes and viewing rate (p < 0.05). Conversely, authors with a financial interest and lower quality and less reliable videos were more likely to recommend DIY aligners. Consumers sought DIY aligner treatment due to a reduced cost. Conclusions: YouTube should not be considered as a viable nor reliable source of DIY aligner information for patients or the public. Dentists/Orthodontists should be encouraged to publish comprehensive and more informative YouTube content related to DIY aligners.

Abstract Background/objective The alternative use of Orthodontic Miniscrew Implants (OMIs), traditionally used for skeletal anchorage, to facilitate micro-osteoperforations (MOPs) for accelerating orthodontic tooth movement has been reported in previous studies. The objective of the present in vitro study was to compare the microdamage generated by OMIs and MOP-purposed screws of similar dimensions in porcine cortical bone. Materials and methods Forty rectangular porcine cortical bone specimens of 1.5 mm thickness were produced and divided into two equal groups. According to group allocation, either a single MOP screw or OMI was inserted and later removed. A sequential staining protocol was carried out to distinguish true microdamage created upon screw insertion and removal from iatrogenic damage. The bone specimens were imaged by a confocal laser scanning microscope, and five histomorphometric measurements described and quantified the generated microdamage. Results On the entry (outer) bone surface, the OMI screws produced greater microdamage which reached statistical significance across all of the histomorphometric parameters. In contrast, a statistically significant increase in microdamage was created following MOP screw insertion on the exit (inner) bone surface, but only in three assessment parameters, recorded as total damage area, as well as diffuse damage area and radius. Conclusions Overall, the present study showed that 1.5 mm OMIs produced slightly greater microcrack-type and diffuse damage-type microdamage than the 1.6 mm diameter MOP screws. However, these differences were small and considered clinically insignificant.

Abstract A maxillary transverse deficiency is a common craniofacial problem. Rapid palatal expansion (RPE) has been traditionally considered for the treatment of children and young adolescents, but this is not applicable in late adolescents or adults due to the ossification of facial sutures. A surgically assisted rapid palatal expansion (SARPE) was initially advocated for this group of patients, but the surgical procedure is associated with morbidity. As temporary anchorage devices (TADs) have been recently and popularly applied in clinical orthodontics, micro-implant-assisted rapid palatal expansion (MARPE) has been employed to facilitate maxillary expansion in skeletally mature patients. There have been various proposed MARPE designs and the outcomes appear promising. The aim of the present article is to discuss the role of MARPE in clinical orthodontics by reviewing its background, design, indications, treatment effects, stability, and limitations in the current literature. The treatment effects of two types of MARPE, bone-borne and tooth-bone-borne (hybrid), will be individually assessed.

Abstract Objectives The aim of this prospective study was to assess the amount of interlabial gap (ILG) and freeway space (FWS) at rest position (RP) according to gender, age, and skeletal pattern, and to evaluate the cephalometric measurements at maximum intercuspal position (MIP) and at RP to define the cephalometric changes from MIP to RP related to the amount of ILG and FWS. Methods Lateral cephalograms and photographs of selected subjects (47 females, 57 males) were obtained at MIP and RP. Cephalometric measurements at MIP and RP and their differences were measured and compared. Results ILG (P > 0.05) and FWS (P < 0.01) were greater in males than in females. ILG (P < 0.05) and FWS (P > 0.05) were greater in adolescents than in adults. ILG and FWS were not significantly related with the vertical skeletal pattern (FHR, facial height ratio). ILG was the greatest in Class II cases but without significance. FWS was significantly greater in Class III than in Class I and Class II cases (P < 0.05). At MIP, the ILG at RP increased as overjet (P < 0.05) and upper lip to the aesthetic line (P < 0.01) increased. At RP, the ILG increased as upper incisor exposure and the lips to the aesthetic line increased (P < 0.001), and FWS decreased as overbite decreased (P < 0.001). From MIP to RP, lip length showed the greatest decrease (P < 0.001) in the large ILG group. Additionally, Bjork sum (the sum of the saddle, articular, and gonial angles), mandibular plane angle, anterior facial height, and ANB (P < 0.001) showed the greatest increase, while OB (P < 0.001) showed the greatest decrease in the large FWS group. The lip competent group showed the largest frequency distribution in the small ILG and FWS groups, while smile line frequency distribution showed no relationship with the level of ILG and FWS. Conclusions Taking cephalometric measurements at RP would be helpful to evaluate the ILG and FWS more accurately, and to provide a more accurate diagnosis and treatment plan.

Abstract Objective The aim of the present study was to evaluate the quality of information uploaded onto the Internet regarding accelerated orthodontics. Materials and methods The selected search terms ‘accelerated orthodontics’, ‘rapid orthodontics’, ‘speed orthodontics’, ‘rapid braces’, and ‘speed braces’ were searched by three commonly used search engines (Google, Yahoo, and Bing), and the URLs of the top 50 websites were recorded. The websites were evaluated using DISCERN, HONcode, and the Journal of the American Medical Association (JAMA) benchmark instruments. The readability of the websites was evaluated by the Flesch Reading Ease Score (FRES) and the Flesch-Kincaid Grade Level (FKGL). Results The total mean DISCERN score (section 1 + section 2) for all websites was 29.50/75 (range: 15–68). The average FRES of all websites was 52.99 ± 31.91. Also, the average FKGL score of all websites was 10.73 ± 2.03. Professional health organisation websites had significantly higher DISCERN scores than other websites (p < 0.001). Only three websites had the HONcode seal. Professional organisation and private dental practice websites showed better compliance with JAMA benchmarks. There was no statistically significant difference related to FRES and FKGL scores between groups (p > 0.05). Conclusions Information regarding accelerated orthodontics found on the Internet is insufficient. It is recommended that orthodontic societies and orthodontists increase the quality of the websites which describe accelerated orthodontics.

Abstract Objectives The aim of this study was to evaluate the use of functional appliances by the currently practising orthodontists in Malaysia. The objectives were to identify the different types of functional appliances used by Malaysian orthodontists and to investigate the variation in treatment protocols when attempting growth modification. Methods An online questionnaire consisting of 24 open-ended and multiple-choice questions was emailed to members of the Malaysian Association of Orthodontists (MAO) (n = 183). The survey was based on a previous study conducted by members of the British Orthodontic Society and was modified to suit the Malaysian population. The data were analysed using SPSS to generate frequency tables and descriptive statistics. Results Seventy-two responses were received from current Malaysian orthodontists. Of the respondents, 71% practised in a government setting and 29% were in private practice. The Clark Twin Block was the most frequently used functional appliance by 90% of Malaysian orthodontists. Many of the respondents (57%) prescribed full-time wear of removable functional appliances for 6–9 months (except during mealtimes) (51%). Following active removable functional appliance therapy, 91% prescribed a period of retention which involved a reduction in the duration of wear. The retention phase extended for 2 to 3 months (41%) or for 4 to 6 months (39%) for the majority of the respondents. Conclusions The Clark Twin Block is the most frequently-used functional appliance for the management of a Class II malocclusion by orthodontists currently practising in Malaysia.

Abstract Cleft lip and palate (CLP) are conditions that require long-term management and review from infancy to adolescence. Surgical procedures become easier when nasoalveolar moulding (NAM) measures are applied during the neonatal period. Orthodontic treatment provided for these patients during the progressive dentition developmental periods can achieve positive aesthetic and functional results. In patients affected by a CLP, the lateral incisor in the cleft region is usually missing and multidisciplinary prosthodontic rehabilitation of the edentulous space is often required. In the present case report, positive results of NAM, coupled with orthodontic and prosthodontic treatment are presented for a CLP patient who began management during the neonatal period. In addition, a minimally invasive aesthetic restoration is presented as a solution for the prosthodontic rehabilitation of a missing lateral incisor.

Abstract Background The importance of assessing patients for paediatric obstructive sleep apnoea (OSA) cannot be more highly stressed and orthodontists may play an essential role in risk screening. The Paediatric Sleep Questionnaire (PSQ) is a validated tool to identify whether a child is at risk for paediatric OSA. Objectives The likelihood of paediatric OSA in school-aged children residing in Far North Queensland (FNQ) will be assessed using the PSQ. Methods Parents of children aged between 4 and 18 years were invited to participate through schools and social media messaging to complete an online PSQ questionnaire to assess their OSA risk and demographics. Results The final sample consisted of 404 school-aged children of whom 62.5% were found to be at a high-risk for paediatric OSA. The high risk was significantly associated with males and those of overweight/obese BMI status (p < 0.001). Race and age were not significant associations (p > 0.05). Conclusions Within the contributing sample of school-aged children in FNQ, a significant number were found to be at high-risk of paediatric OSA. Males and overweight/obese children were measured risk factors.

The high risk was significantly associated with males and those of overweight/obese BMI status (p < 0.001). Race and age were not significant associations (p > 0.05). Conclusions Within the contributing sample of school-aged children in FNQ, a significant number were found to be at high-risk of paediatric OSA. Males and overweight/obese children were measured risk factors.","PeriodicalId":48559,"journal":{"name":"Australasian Orthodontic Journal","volume":"37 1","pages":"197 - 205"},"PeriodicalIF":0.4,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47997370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Aims This article presents the nonsurgical orthodontic treatment of a skeletal Class III malocclusion of an adult patient. Methods Because the patient refused an orthognathic surgical procedure, the mandibular first premolars were extracted and orthodontic camouflage using miniscrew anchorage was used to correct dental asymmetries and the occlusal relationship. Results The treatment strategy was successful and provided an acceptable aesthetic functional occlusion. Conclusion When appropriately indicated, the orthodontic camouflage of a class III malocclusion can avoid orthognathic surgery and, through the use of mini-implants as skeletal anchorage, enhance the results.
